CELLAR FOR AXLE-BOXES.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed March 22. 1907- Serial No. 363,811.

' cellar for axle boxes, and especially such as are used in connectionwith locomotive and truck axles where the boxes are located inside thewheels, which will effectively exclude dust and dirt from the bearings.

With this end in view my invention consists in a cellar having movableguards at the ends and sides which are pressed outwardly by springs soas to maintain frictional contact with the axle and box under allconditions of service.

It further consists in certain novelties of construction andcombinations of parts hereinafter set forth and claimed.

The accompanying drawings illustrate two examples of the physicalembodiment of the improvement constructed according to the bcst modes 1have so far devised for the practical application of the principle.

Figure 1 is a view in perspective of the preferred form of constructionof the cellar, the same being rc moved from the box. Fig. 2 is an endview of Fig. l with one end guard in section. Fig. 3 illustrates inperspective the second example of the cellar. Fig. 4 is a cross sectionof Fig. 3.

Referring to Figs. 1 and 2, the letter A, designates the bottom of thecellar; B, the side walls; C, the end walls; D, the curved upper edgesof the end walls; E, the movable guards for the end walls, each of saidguards having a curved or concave flange F at the top, and two parallelwings G, G, extending downwardly from the flange and one' upon each sideof an end wall, as shown; H,'a spring for forcing the guard upwardlyagainst the journal, and l are side guards of textile material supportedat their ends by the end guards so as to move with said end guards.

To hold each side guard securely and prevent the same from sagging theupper edge K may be passed around a rod or wire L and stitched orotherwise fas toned, and the ends M of the rod or wire may .be insertedwithin holes N in the end guards and upset as clearly shown by Fig. 2.

Obviously when the cellar is in position between the jaws of the box thesprings will force the flanges of the end guards against the undersurface of the journal, and the guards at the sides will lie adjacent toor frictionally engage the sides of the axle or box, and dust and dirtthus be excluded.

Referring to the second example, Figs. 3 and 4, the numeral 1 designatesthe bottom of the cellar; 2, the sidewalls; 3, vertical recesses formedin each of the side walls; 4, two vertical slots in the outer portion ofeach wall; 5, guards located within the recesses and with their edgesprojecting therefrom; 6, pins with their inner ends fixed in the guardsand their outer ends movable within the slots 4, -'l, the function ofsaid pins being to retain the guards within the recesses; 7. springs,one occupying the space at the bottom of each recess 3 and bearingagainst the lower edge of a guard and forcing it outwardly; 8, the endwalls made double like the side walls; 9, the curved upper edges of theend walls; 10, recesses in the end walls; 11, movable guards within therecesses 10 as shown; 12, the curved flange at the top edge of eachguard; and 13 are the springs located within the recesses 10 and bearingagainst the lower edge of the guard.

The body of the collar is preferably cast in one piece but may beotherwise constructed, and the bottom thereof, as well as that of thefirst example shown by Figs. 1 and 2, may be provided with perforatedlugs for the reception of means to hold the cellar in place relative tothe box and beneath the axle. When the collar is in operative positionthe flanges of the guards at the edges of the cellar bear against thelower surface of the axle and are held in close frictional contacttherewith by the springs. The guards at the sides are also pressedoutwardly by the springs beneath them, as shown in the crossscctionalview, so that the upper edges are in frictional contact with the axle orbox under all conditions of service.

From the foregoing description taken in connection with the drawings itis clear that l have provided a cellar which when secured to an axle boxand in use will exclude (lust and dirt from the box and the bearingsurfaces of the brass andaxle.

What I claim is:

1. The combination with an axle box cellar having a bottom, end walls,and side walls, of guards at the sides; and springs for forcing the sameupwardly.

2. The combination with an axle box collar, of end guards, side guardsof textile material, and springs for forcing said guards upwardly.

K. The combination with an axle box cellar having a bottom. side wallsand end walls, of end guards; Side guards connected to the end guards;and springs for the purpose set forth.

4. The combination with a cellar having a bottom, side wills and endwalls, of end guards each having Wings located each side of an end wall;and a spring beneath each end guard.

5. The eunhlnntion with a cellar having a bottom, side walls and endwalls, of side guards of textile material for excluding dust and dirtfrom the axle hearing at the sides thereof, and means for supportingsaid guards.

In testimony whereof I ailix my signature in presence of two witnesses.
